Maine Application June 19, 1950, Serial No. 168,869

This invention relates tonew and useful improvements in binding and/or covering machines, and the primary object of the present invention is to provide a machine for binding the edges of a shoe platform and which is also adapted for applying binding tape to the edges of any suitable article, such as book coverings, or the like.

Another very important object of the present invention is to provide a binding machine involving a pair of reciprocating hammers and a spool located behind the hammers and coacting with the hammers to fold a binding tape into a channel as the binding tape is forced between the hammers and against the spool by an article that is to be bound.

Yet another object of the present invention is to provide a binding or covering machine of the aforementioned character involving a novel and improved mechanism for tensioning the binding tape when the tape is forced between the hammers and against the spool.

Another object of the present invention is to provide a binding machine wherein the bindingtape tensioning means involves a sliding wedge which is manually actuated to activate the tensioning means.

A further object of the present invention is to provide a binding machine including a pair of vertically swingable, spring connected hammers and a rotary cam for simultaneously riding against the hammers to spread and then release the hammers, whereupon the hammers will be urged toward each other to tamp or clamp a binding tape against both faces of an article bein bound.

A still further aim of the present invention is to provide a binding machine that is simple and practical in construction, strong and reliable in use, small and compact in, structure, efficient and durable in operation, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.-

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Referring now to the drawings in detail, wherein, for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I0 represents a frame having a pair of vertically swingable, upper and lower hammers l2 and M on one of its end walls. The upper hammer I2 includes a supporting arm I6 that is secured to the frame through the medium of a horizontal pivot I8 and the lower hammer 14 also includes a supporting arm that is pivoted to the frame by a horizontal pivot 22. I

The arms 16 and 20 support laterally projecting pins 24 and 26 that engage the ends of a coil spring 28. The spring 28 yieldingly urges the arms I6, 20 and hence the hammers l2, M toward each other as shown best in Figure 5. A vertical guide strap 301s secured intermediate its ends to the frame It] and the arms 16 and20 are positioned between the strap 30 and the end :a cam 34 having diametrically opposed lobes for riding against the lower edge of the arm l6 and the upper edge of the arm 20 to urge the arms apart, whereupon the spring 28 will return the hammers l2, M to a position for tamping binding tape against an article. I

The arm I6 is integrally formed with a sleeve 36 that slidably receives the hammer l2 and which supports a set screw 38 that is manually adjustable to retain the hammer I2 vertically adjusted in the sleeve 36.

The end of the shaft 32 remote from the cam 34 supports a pulley 40 that is connected by a pulley belt 42' to a suitable source of power I such as a motor (not shown) which is located 3 close to the frame I0. The shaft 32 is received in bushings 44 at the ends of the frame.

A holding arm 46 is detachably secured to and held stationary on the frame I and underlies the arm 20. The arm 46 is provided with a forward oii'set portion 48 that supports a plurality of guide posts to whose upper hollow and conical ends :2 receive balls 84 that are supported on lugs 56 within the ends 52.

A pair of horizontal cars 58 project forwardly from the frame IU ao acent the hammers and supports a vertical spool 60 that parallels the hammers I2, I4 and Which is located behind the hammers. The area of the roller or spool between its upper and lower flanges registers with the space between the hammers for a purpose later to be more fully described.

The forward hat race or the frame I0-supports a bracket 62 having an upper horizontal flange 64 that rotatably supports a vertical adjusting screw 66. A traveling member or nut 68 is threaded on the screw 66 and is rigidlysecured to the inner leg portion I0 of a guide channel I2. The guide channel extends longitudinally of the frame and includes an exit end I4 that is spaced from the spool 60. The nut 68 is fixed to a guide plate 16. whose vertical sideedges are slidable in keyways I8 in the sides of the bracket 62.

The forward face of the frame I0 supports a shelf or plate 80 on which there is mounted a horizontally swingable member or arm '82 that is secured to the shelf 80 by a horizontal pivot 84. One end of the member.82 is provided with an upstanding post 86 that supports a vertical pressure roller 88. A horizontal screw 90 is threaded in a horizontal aperture in the arm '82 and supports at its inner end a" disk'82 that enters a. horizontal recess 94 in the frame I0. A spring 98 seated within the recess 94 bears against the disk 92 and yieldi'ngly urges the roller 88 through a slot S in the outer flange of channel I2 and against the vertical face of the inner flange of the guide channel at the exit end of the guide channel.

A guide sleeve 98 is s'ecured'to the plate 80 on the frame remote from'the hammers and slidably receives a vertical wedge I00 to which there is threaded a screw I02. The screw I02 isattached to a vertically swin'gable foot lever or pedal I04 by a connecting member I06. The sleeve 98 is provided with a horizontal slot I08 that slidably receives one end of the member 82, as shown best in Figure 7. A spring I IOis mounted in the lower end of the sleeve 98 and urges the wedge I00 to its raised position and against the member 82. y I

As the pedal I04 is pressed downwardly, the wedge I00 releases the member 82 and the spring 96 urges the member 82 to a position whereby the roller 88 is forced toward theframe.

The leg portion I0 of the channel 12 is provided with an end extension II2 that enters a vertical slot H4 in a gauge member II6. A set screw H8 is carried by the'member H6 and is threaded in the upper edge of the extension I I2 to adjust the member II8 vertically of the guide channel and so that-the lower flat and horizontal face I20 of the member '6 may b'ear'a'gainst the upper edge of a binding tape T.

A vertical turn roller I22 is mounted on the guide channel or the member I I2 and is positioned relatively close to the spool 60, as shown in Figures 1 and 2,. to curve or turn the tape.

In practical use of the present invention, the binding tape T is extended through the guide channel I2, behind the roller 88 and in front of the hammers I2 and I4. Next, the article A to be bound, such as a shoe platform, is forced between the hammers and toward the spool 60 so that the tape T will be folded into a channel. The tape will be forced against the spool 60 and between the upper and lower flanges of the spool, by the article A, as shown in Figure 6.

Then, the pedal I04 is depressed to cause the wedge I00 to release the member 82, whereupon the spring 96 urges the roller 88 against the binding tape T and the binding tape against the flat vertical face of the frame to retain the tape taut and tensioned.

As the pedal I04 is released, the shaft 32 r0- tates and the cam 34 reciprocates the hammers to tamp the binding tape against both faces of the article A. The tape T is preferably coated with adhesive or the article A is coated with adhesive to retain the tape on the article and the article is rollingly supported upon the rollers or balls 54 as it is fed betweenthe hammers and toward the spool.

After the tape has beenattached to the article, as the article is swung counter-clockwise, the tape will be pulled through the guide channel and the tape is ten'sioned at will by a depression of the pedal I04.
